Hi djbmechanical,
QuickBooks abbreviates Staffordshire as ST for customer-facing address when sending invoices.
As a workaround, you can include Staffordshire in parentheses next to the city name in the customer-facing address. Here's how:
- Click on the Gear icon, then choose Account and settings.

- Choose Company tab.
- Under Customer contact info, select Customer address.
- Add Staffordshire in parentheses after the city name.
- Hit Save, then Done.
